I sent the application via their web app. They contacted me a couple of days later. I spoke with the recruiter over the phone, and we arranged two phone interviews for a month later. Each interview was one hour long and conducted with a different engineer, back-to-back on the same day.

The interviews were very technical, focusing on algorithms and object-oriented design.

After about a week, they asked me to arrange a new phone interview, again scheduled for a month later. The recruiter informed me that I had passed and that she was looking for a host for my internship. More than six weeks passed, and the recruiter was unable to find a host for me. I was approaching the deadline for host-matching and was very frustrated.

Suddenly, one Friday afternoon, I received an email from the recruiter stating that she was about to start her maternity leave and that I had been transferred to another recruiter. This new recruiter found a perfect host match within a few hours.

I believe the first recruiter was not very interested in finding me a host, perhaps she was more concerned about her maternity leave.

I received the offer via airmail and signed it. The company was a great help with all the visa paperwork.

Given a number with some digits, for example 5412, calculate the minimum number with the same exact digits that is larger than the original.

In this case, it will be 5421. It has the same digits (1-2-4-5). From all combinations larger than 5412, it is the smallest.
